IFR
The IFR function in the DUSART provides a configurable CODEC designed for the transmission and
reception of infra-red data frames. Input signals should be demodulated externally before being
supplied to the device for decoding. The IFR transmit data output signal may be provided both
modulated and unmodulated.
The module is designed to be flexible, supporting current consumer protocols (RC-5, ASK, PPM) and
other infra-red protocols. Some support is also provided for low-rate IrDA format signals.
SCI
The Smart Card Interface (SCI) function in the DUSART contains all of the logic functionality required
for the terminal (controller) part of a smart card interface. Activation and deactivation sequences are
supported with various degrees of (configurable) automation. Protocol type T=0 is supported; refer to
the Smart Card standard ISO 7816 parts 1-10.
The SPI function includes the following features.
•

USR
The USR function provides flexible, low-level access to the core features of the DUSART peripheral. It
may be used to implement synchronous or asynchronous protocols that are not already supported by
the other DUSART functions, for example a 9-bit UART protocol, with less software overhead than a
GPIO based emulation.
The USR function includes the following features.
